I used my Mini to "dust" a flyer off a tree. I touched the leaves too many times and they fell off. The front arm was broken. I thought I would never break it. LAUGH OUT LOUD. I've spent 17 years in the hobby business so if I can get a part I can replace it. I watched a video on the internet and did the repair. The spring-loaded pivot caused most of the mounting problems. You need to twist and push it in under some spring tension. Put props and flew. I've spent several hours with it with no problems.
